A nine-year study by UCLA biologists says the reason often has to do with "obtaining priority access to females" in the area.The scientists observed and analyzed the behavior of several species of Hetaerina damselflies, also known as rubyspot damselflies. For the study, published this month in the print edition of the journal Proceedings of the Royal Society B, researchers observed more than 100 damselflies a day in their natural habitat along rivers and streams in Texas, Arizona and Mexico.

Cleaner buses could result in fewer school absences The use of clean fuels and updated pollution control measures in the school buses 25 million children ride every day in the United States could result in 14 million fewer absences from school a year, based on a study by the University of Michigan and the University of Washington. In research believed to be the first to measure the individual impact on children of the federal mandate to reduce diesel emissions, researchers found improved health and less absenteeism, especially among asthmatic children.
